than the one shown and described in U. S. Letters Patent No. 2,131,347.

Referring now to form of my invention:

Fig. 1 is a plan view installation;

Fig. 2 is a plan view of the socket installation as viewed from thesocket side;

Y Fig. 3 is a plan View of the stud installation as viewed from the studside;

Fig. 4 is a view of the stud installation as viewed from the attachingring side; and

Fig. 5 is an enlarged section of the complete installation taken on theline 5-5 of Fig. 1.

Referring now to the particular disclosure of my invention illustratedby the drawings, I have shown a so-called laundryproof snap fastenerinstallation. This installation includes a socket installation (Fig. 2)and a stud installation (Figs. 3 and 4) forming a complete installationas shown in Figs. 1 and 5.

The socket installation is preferably of the type shown in U. S. LettersPatent No. 2,131,347 and includes a socket member an attaching ring 2and a socket carrying material 3. The socket member I has astud-receiving aperture 4 surrounded by suitable yieldable stud-engagingmeans 5 and the face of the socket has an annular recess 6, the purposeof which will be described later.

The stud installation includes the main feature making my inventionpossible and comprises a snap fastener stud 1, an attaching member 8,and a stud-supporting material 9. The stud is of the usual type, butpreferably has a very small base flange H). The attaching member ispreferably in the form of a ring having a central the drawing showingone of the complete fastener II and a number of spaced attaching theaperture H, as shown in Fig. 1. For assembly of the stud installation,it is merely necessary to support the stud l and attaching member 8, bysuitable attaching tools, hold the stud-supporting material betweenthem, and then move the tools together, by any suitable means, therebyforcing the ends of the prongs 12 through the material and curling themover the flange It, as shown in Figs. 3 and 5. With this constructionthe stud flange is small enough so that it forces the material 9 intothe aperture ll (Fig. 5) and has a tendency to nest with the attachingring, thereby forming a relatively thin installation.

When the stud and socket installation are in snapped together relation(Figs. 1 and 5), a very thin installation results because of the factthat curled ends of the prongs l2 and the base flange ll] may enter therecess 6 in the socket I, as best shown in Fig. 5.

The type of fastener installation just described is particularlydesirable when the supporting material is knit goods and when a verythin application is required. The conventional type of fastener studassembly usually cuts thethreads of knit goods and permits unraveling ofthe threads. The pronged ring attachment overcomes this trouble and myinvention both overcomes the trouble and provides a thinner installationthan anything known heretofore. When knit material is used, it isadvisable to provide a reinforcing strip because it strengthens theinstallation and takes the stretch out of the material adjacent to thefasteners, thus making it easier to unsnap the studs and sockets. I haveshown a reinforcing strip 13 in the socket assembly and another strip 14in the stud assembly.

My invention is particularly useful on knit childrens garments,sweaters, and applications where thickness must be kept to an absoluteminimum while providing for ready engagement and disengagement of thesnap fastener stud and socket.

While I have illustrated and described one preferred embodiment of myinvention, I do not wish to be limited thereto, as the scope of myinvention is defined in the following claim.

I claim:

A snap fastener stud installation comprising.

aperture prongs l2 surrounding a flexible sheet material support, a studmember having a laterally extending base flange bearing on one face ofsaid sheet material support, and an attaching ring bearing on theopposite face of said sheet material support, the inner edge of saidring being substantially outside any projection of the peripheral edgeof said base flange into the plane of said ring, said attaching ringhaving attaching prongs extending from and spaced about the inner edgethereof through said sheet material support, said prongs being curledover to overlie said base flange to secure said stud 'member and saidattaching ring to opposite faces of said sheet material support and tosecure a ring portion of said sheet material support between theperipheral edge of said base flange and said inner edge of saidattaching ring.
